THEODORE AUGUSTUS EISEN, OF LOS ANGELES, CALIFORNIA.

BUILDING.

To all whom it may concern:

' Beit known that I, THEODORE AUGUSTUS EISEN, of the city of Los Angeles, in the county of Los Angeles, in the State of California, have invented certain new and useful Improvements in Buildings, ofwhich the following is a full, clear, and exact specification, reference being had to the annexed marked thereon. l

' -My said invention which relates to certain improvements in buildings, is more particularly adapted for the construction of were houses, hotels, office buildings, and other architectural structures generall wherein is a succession of vfloors each-above another and supported on columns in spaced parallel rows between the outer walls of the buildings or in thewalls themselves.

The object of'my'apresent improvementsis duce or construct such buildings thefloors are carried by cantaliver on the upperparts .of the columns, where y the cantaliver platforms and the floors are'supported', and the arran to pro wherein ment of the construction issuch that the cantaliver platforms need not be placed on the columns, and need not receive and carry until after the columns and the girders which constitute the carrying ed es thereofat each side of eachcantaliver platform, and throughout the entirety of each floor, are connected. 1 a

In carrying my invention into practical effect, after the position of the several ,columns has been determined, floor carrying girders which may be of metal, reinforced concrete, wood, burned fireclay, or other material, are placed in position at certain distances from the outside of the columns as determined'by the desired size of the cantaliver platforms in order to be. permanently cdnnected to the cantaliver platforms, and prior to the said cantalivers being constructed or placed, these girders are to be temporarily carried at the required levels corresponding to the floors of the structure, by being temporarily supported upon uprights, or a framing of timber, or other material.

After the aforesaid girders of each floor, and the portions thereof constituting the sides of each cantaliver platform are tied together, and to the columns by reinforcing ties, or united by braces, or their equivalents, then the frame constituted of those portions of permanently placed and Specification of Letters Patent.

the aforesaid-girders which are to become the sides or edges of the cantaliver plat- ,of cast, riveted or rolled metal, covered or not covered with cement or concrete, or of wood, or of reinforced fireclay, or terra cotta or of reinforced concrete, the whole of which materials are'now'used as the material for the columns of buildin' "After the concreteconstitutlng the body of each dantaliver has com letely set, or the aforesaid braces are secured in the structure, then the cantalivers take the weight of the rders in each entire floor, this being efected by knocking out the temporar right props, or su porting frame of timber upon which the door-carrying irders are supported during their assembling, and while being uni-ted at the several angles where thosegirders meet to form the sides and edges -'of the portions of the cantalivers all in the manner hereinafter set forth, The

spaces between the girders of each floor,

parts of whichconstitute the sides and edges are filled in with crete, or other material. arranged in spaced parallel rows with cantaliver platforms on the columns and girders or beams arranged on the edges of the plat, form, each girderextending from one 1 latform to the'next of the adjacent co umn the ends of the platform edges, there being a girder for each platform edge, excepting those situated on the outside.

U on the annexed drawings: Figure 1, is a pian showing the meeting ends of the girders at any place in the floor of a build- .mg wherein the nds of adjacent girders meet for the purp ses of being united at the locus of a column where a cantaliver is to be constructed to "carry the floor after the said girders'havefbeen assembled, and tied together in the-plates where such cantalivers are to be formed. Fig. 2, is a plan corregirders being flush with thesponding to Fig. 1, showing the said meeting ends of thegirders united,'and the con wherein'several cantaliverplatforms, and

Fig. 8, is a plan on a larger scale than Fig. 1, showing the rods, or by reinforcing rods alone, that is to meeting ends "of four girders at the place wherethey 'unite 'for forming the edges of .a cantaliver' platform, and which are united by reinforcing ties connected to the webs of saidgirder's, and passing around a column of-H section at the center, upon which the cantaliven platform-is to be carried? Fig. 9,

is a plan-corresponding to Fig. 8 wherein. concrete'is-used to inclose the reinforcing nods shpwn. in Fig. 8, in the form of'a cross, whosexa'rms stretch from oneangle to the diametrically opposite an 19 ofthe 's uare formed by 'such meeting 0 the said gir cm; the spaces between the concrete in. the cruciform shape being left unoccupied or empty; I -Fig."10, 1"s a section on;the line 0, 0,,Fig. 9.

Fig. 11, is a horizontal section, showing the meeting ofth'e reinforcing rods, an angle iron at' the place of meeting of two girders i at"right angles to each other, and the reinforcin rods extending from said angle iron. As s own by Figs. 1, 2, and 3, the adjacent endsfof the girders. 1, constitute-a rectilinear figure around the loci where the supporting bull ing. 1, may e column 1 1, is situated, and constitute a frame tobe afterward filled'by the concrete formlat-forms of the in art of the'cantaliv'er The meeting ang es ofthe girders united in various ways, but a convenient methodof uniting the same is shown at Fig. 6, wherein the girder 1, shownin transverse section is unitetifoneiich of its sides to anothergirder 1, projecting at right angles thereto. The girders 1, and 1, are

connected by the angle irons 2, respectively, p

tension .and compr'ession reinforcing rods 4:,

.situated at any suitable angles within '-the frame formed-by the meeting and union of the ends'of the'girders 1,-so as to provide transverse compression and tension, of the rods 4, in as many times as are sufiicient to produce the requisite stiffness of the cantalivers whencompleted. To complete a cantaliver of which the frame and central column is shownat- Fig. 1, concrete is poured into the hollow rectangular space constituting the cantaliver frame, a temporary bottom or mold'being placed beneath the frame formed by the girders 1, upon which the concrete. rests after being poured and while setting. In every .su'ch rectangular frame reinforcedas hereinbefore described, and as s hownat Figs. 1, and 2; of the drawings, the

concrete when it has set therein, constitutes the solid body of.the cantaliver platform, which may be either in one piece with the columns 11, thereof, or there may be a.joint whereby every column and its corresponding cantaliver platforms are not united. For general purposes, however, the column 11, is a vertical steel or iron beam of an H shape section, around which concrete'is poured and sets in the same manner as it sets within the frame of thecantaliver platform, or the columns Ina be constructed of reinforced concrete or reclay,-iron, wood, or other material. So long as the girders 1, are not connected. by the concrete of the cantalive'rs with the columns, and while placing the girders 1, in their \proper relative ositions for beinguni'ted in frames at the co umns where the cantaliver platforms, are to be constructed,-these girdersl, rest upon the temporary timber supports 5, Fig.1, or 'iapon" analogous supports which} are remove soonas the concreteof thecantalivers has set and united with. thecantalivers 6, and the girders 1,' with the columns 11, after which the flooring, consisting of floor beams, joists,

or slabs 7, of reinforced concrete, steel or other material, are placed in position and supported by: girders constituting the sides and edges 0 t e cantaliver platforms. I

p In Figs. 1, 2,.an'd 5, of the annexed drawings, I have shown the concrete 8,as filling the entire space of each of the rectangular frames formed at the loci of the .columns 11, but in place of filling the frames entirely wit-hc'onc'rete' the concretemay occupy a portion of the said frames only, in the form -of a cross 9,-as shown at Fig. 9, or in any other suitable form, whereby'portions of the space within the rectangular frames are not filled by concretefi, Z

.The form ofcmicrete shown at Fig. 9, is

very conveniently applied when the rectangular frames formed by the meeting ofportions of the girders 1, are connected to? gether diagonally by reinforcing rods 10, as shown at Figs. 8,10, and 11, and the concrete when so applied as shown at Fig. 9,

completely incloses the upper tension rods 10, and the lowercbmpression rods 10. By such construction a cantaliver platform containing less'concrete is obtained than by the construction hereinbefore described with reference to, and shown at Figs. 1, 2, 3, 4, and 5. It is to be understood that the girders may be of any section adapted for the purposes of this invention.

I claim as my invention. 1. In a building construction, a series of columns; in spaced parallel rows, the columns having enlargements comprising cantaliver platforms of a roximately rectangular shape, a series 0' o'er girders extend ing from column to column, and at right angles to each other, each girder lying against an edge of the cantaliver platform and the end thereof flush with an adjacent edge of the platform and in abutting relation with the girder thereagairlst, substantially as set forth.
